Indian Craniometric Variability and Affinities

Table 3

Relationship between measurements’ mean and standard deviation for Indian series.

Measurements included	Untransformed variables		Variables transformed to base 10 logarithms
	Pearson’s 𝑟	Slope of best-fit line	Pearson’s 𝑟	Slope of best-fit line
All measurements, all series	0.743	0.033	0.839	0.429
All measurements except fractions, all series	0.812	0.034	0.861	0.424
All measurements except fractions, all series with ≥30 values per measurement	0.887	0.032	0.907^a	0.411^b

aPearson’s 𝑟 value is 0.908 for northern Indians and 0.907 for southern Indians.
^bSlope of best-fit line is 0.408 for northern Indians and 0.413 for southern Indians.
